Elizabeth Olsen thinks 'Captain America: Civil War' will be the ''best one'' in the franchise.

The 26-year-old actress - who plays Wanda 'Scarlett Witch' Maximoff in the forthcoming Marvel flick - has praised lead star Daniel Brühl who is the main protagonist in the superhero movie and gushed about how ''incredible'' he is and that she can't wait to see the finished film herself.

She said: ''I think it's going to be the best one. I am very excited to see it myself -- I only worked on set for five weeks, so I wasn't there for the majority of it. Daniel Brühl is an incredible actor and he's playing the main villain in it, and he's incredible.''

The blonde beauty has also hailed the eagerly anticipated motion picture to be ''darker'' than any of the others because it's about real human emotions rather than robots.

She told French magazine Premiere: ''It's a movie about people, as opposed to robots this time.So it's darker and it's allowed to be darker because it gets more in the mindset of humans rather than machines.''

Elizabeth will appear in 'Captain America: Civil War' in 2016, alongside the likes of Robert Downey Jr., Scarlett Johansson and Chris Evans.
